    [use case]

    Returns a new immutable sequence containing the elements from the left hand operand followed by the elements from the right hand operand. The element type of the immutable sequence is the most specific superclass encompassing the element types of the two operands.

    Example:

    scala> val a = LinkedList(1)
    a: scala.collection.mutable.LinkedList[Int] = LinkedList(1)
    
    scala> val b = LinkedList(2)
    b: scala.collection.mutable.LinkedList[Int] = LinkedList(2)
    
    scala> val c = a ++ b
    c: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2)
    
    scala> val d = LinkedList('a')
    d: scala.collection.mutable.LinkedList[Char] = LinkedList(a)
    
    scala> val e = c ++ d
    e: scala.collection.mutable.LinkedList[AnyVal] = LinkedList(1, 2, a)
    B

    the element type of the returned collection.

    that

    the traversable to append.

  6. def ++:[B >: Node, That](that: collection.Traversable[B])(implicit bf: CanBuildFrom[NodeSeq, B, That]): That

    As with ++, returns a new collection containing the elements from the left operand followed by the elements from the right operand.

    As with ++, returns a new collection containing the elements from the left operand followed by the elements from the right operand.

    It differs from ++ in that the right operand determines the type of the resulting collection rather than the left one. Mnemonic: the COLon is on the side of the new COLlection type.

    Example:

    scala> val x = List(1)
    x: List[Int] = List(1)
    
    scala> val y = LinkedList(2)
    y: scala.collection.mutable.LinkedList[Int] = LinkedList(2)
    
    scala> val z = x ++: y
    z: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2)

    This overload exists because: for the implementation of ++: we should reuse that of ++ because many collections override it with more efficient versions.

    Since TraversableOnce has no ++ method, we have to implement that directly, but Traversable and down can use the overload.

    B

    the element type of the returned collection.

    That

    the class of the returned collection. Where possible, That is the same class as the current collection class Repr, but this depends on the element type B being admissible for that class, which means that an implicit instance of type CanBuildFrom[Repr, B, That] is found.

    that

    the traversable to append.

    bf

    an implicit value of class CanBuildFrom which determines the result class That from the current representation type Repr and the new element type B.

    returns

    a new collection of type That which contains all elements of this immutable sequence followed by all elements of that.

    [use case]

    A copy of the immutable sequence with an element prepended.

    Note that :-ending operators are right associative (see example). A mnemonic for +: vs. :+ is: the COLon goes on the COLlection side.

    Also, the original immutable sequence is not modified, so you will want to capture the result.

    Aggregates the results of applying an operator to subsequent elements.

    Aggregates the results of applying an operator to subsequent elements.

    This is a more general form of fold and reduce. It has similar semantics, but does not require the result to be a supertype of the element type. It traverses the elements in different partitions sequentially, using seqop to update the result, and then applies combop to results from different partitions. The implementation of this operation may operate on an arbitrary number of collection partitions, so combop may be invoked an arbitrary number of times.

    For example, one might want to process some elements and then produce a Set. In this case, seqop would process an element and append it to the list, while combop would concatenate two lists from different partitions together. The initial value z would be an empty set.

    pc.aggregate(Set[Int]())(_ += process(_), _ ++ _)

    Another example is calculating geometric mean from a collection of doubles (one would typically require big doubles for this).

    B

    the type of accumulated results

    z

    the initial value for the accumulated result of the partition - this will typically be the neutral element for the seqop operator (e.g. Nil for list concatenation or 0 for summation)

    Applies this partial function to the given argument when it is contained in the function domain.

    Applies this partial function to the given argument when it is contained in the function domain. Applies fallback function where this partial function is not defined.

    Note that expression pf.applyOrElse(x, default) is equivalent to

    if(pf isDefinedAt x) pf(x) else default(x)

    except that applyOrElse method can be implemented more efficiently. For all partial function literals compiler generates applyOrElse implementation which avoids double evaluation of pattern matchers and guards. This makes applyOrElse the basis for the efficient implementation for many operations and scenarios, such as:

    • combining partial functions into orElse/andThen chains does not lead to excessive apply/isDefinedAt evaluation
    • lift and unlift do not evaluate source functions twice on each invocation
    • runWith allows efficient imperative-style combining of partial functions with conditionally applied actions

    For non-literal partial function classes with nontrivial isDefinedAt method it is recommended to override applyOrElse with custom implementation that avoids double isDefinedAt evaluation. This may result in better performance and more predictable behavior w.r.t. side effects.

    x

    Tests whether the argument (arg0) is a reference to the receiver object (this).

    Tests whether the argument (arg0) is a reference to the receiver object (this).

    The eq method implements an equivalence relation on non-null instances of AnyRef, and has three additional properties:

    • It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
    • For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
    • null.eq(null) returns true.

    When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

    [use case]

    Produces a new sequence which contains all elements of this immutable sequence and also all elements of a given sequence. xs union ys is equivalent to xs ++ ys.

    Another way to express this is that xs union ys computes the order-presevring multi-set union of xs and ys. union is hence a counter-part of diff and intersect which also work on multi-sets.

    As with ++, returns a new collection containing the elements from the left operand followed by the elements from the right operand.

    It differs from ++ in that the right operand determines the type of the resulting collection rather than the left one. Mnemonic: the COLon is on the side of the new COLlection type.

Inside, the string representations (w.r.t. the method toString) of all elements of this immutable sequence are separated by the string sep.

    Example:

    scala> val a = LinkedList(1,2,3,4)
    a: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2, 3, 4)
    
    scala> val b = new StringBuilder()
    b: StringBuilder =
    
    scala> a.addString(b, "LinkedList(", ", ", ")")
    res1: StringBuilder = LinkedList(1, 2, 3, 4)
    b

    the string builder to which elements are appended.

    start

    the starting string.

    sep

    the separator string.

    end

    the ending string.

    returns

    the string builder b to which elements were appended.

  13. def aggregate[B](z: B)(seqop: (B, Node) ⇒ B, combop: (B, B) ⇒ B): B

    Aggregates the results of applying an operator to subsequent elements.

    Aggregates the results of applying an operator to subsequent elements.

    This is a more general form of fold and reduce. It has similar semantics, but does not require the result to be a supertype of the element type. It traverses the elements in different partitions sequentially, using seqop to update the result, and then applies combop to results from different partitions. The implementation of this operation may operate on an arbitrary number of collection partitions, so combop may be invoked an arbitrary number of times.

    For example, one might want to process some elements and then produce a Set. In this case, seqop would process an element and append it to the list, while combop would concatenate two lists from different partitions together. The initial value z would be an empty set.

    pc.aggregate(Set[Int]())(_ += process(_), _ ++ _)

    Another example is calculating geometric mean from a collection of doubles (one would typically require big doubles for this).

    B

    the type of accumulated results

    z

    the initial value for the accumulated result of the partition - this will typically be the neutral element for the seqop operator (e.g. Nil for list concatenation or 0 for summation)

    seqop

    an operator used to accumulate results within a partition

    combop

    an associative operator used to combine results from different partitions

  17. def applyOrElse[A1 <: Int, B1 >: Node](x: A1, default: (A1) ⇒ B1): B1

    Applies this partial function to the given argument when it is contained in the function domain.

    Applies this partial function to the given argument when it is contained in the function domain. Applies fallback function where this partial function is not defined.

    Note that expression pf.applyOrElse(x, default) is equivalent to

    if(pf isDefinedAt x) pf(x) else default(x)

    except that applyOrElse method can be implemented more efficiently. For all partial function literals compiler generates applyOrElse implementation which avoids double evaluation of pattern matchers and guards. This makes applyOrElse the basis for the efficient implementation for many operations and scenarios, such as:

    • combining partial functions into orElse/andThen chains does not lead to excessive apply/isDefinedAt evaluation
    • lift and unlift do not evaluate source functions twice on each invocation
    • runWith allows efficient imperative-style combining of partial functions with conditionally applied actions

    For non-literal partial function classes with nontrivial isDefinedAt method it is recommended to override applyOrElse with custom implementation that avoids double isDefinedAt evaluation. This may result in better performance and more predictable behavior w.r.t. side effects.

    x

    the function argument

    default

    the fallback function

    returns

    [use case]

    Builds a new collection by applying a function to all elements of this immutable sequence and using the elements of the resulting collections.

    For example:

    def getWords(lines: Seq[String]): Seq[String] = lines flatMap (line => line split "\\W+")

    The type of the resulting collection is guided by the static type of immutable sequence. This might cause unexpected results sometimes. For example:

    // lettersOf will return a Seq[Char] of likely repeated letters, instead of a Set
    def lettersOf(words: Seq[String]) = words flatMap (word => word.toSet)
    
    // lettersOf will return a Set[Char], not a Seq
    def lettersOf(words: Seq[String]) = words.toSet flatMap (word => word.toSeq)
    
    // xs will be a an Iterable[Int]

    Returns a parallel implementation of this collection.

    Returns a parallel implementation of this collection.

    For most collection types, this method creates a new parallel collection by copying all the elements. For these collection, par takes linear time. Mutable collections in this category do not produce a mutable parallel collection that has the same underlying dataset, so changes in one collection will not be reflected in the other one.

    Specific collections (e.g. ParArray or mutable.ParHashMap) override this default behaviour by creating a parallel collection which shares the same underlying dataset. For these collections, par takes constant or sublinear time.

    All parallel collections return a reference to themselves.

    the type of the second half of the returned pairs

    that

    The iterable providing the second half of each result pair

    returns

    a new immutable sequence containing pairs consisting of corresponding elements of this immutable sequence and that. The length of the returned collection is the minimum of the lengths of this immutable sequence and that.

    Implicit information
    This member is added by an implicit conversion from Comment to NodeSeq performed by method seqToNodeSeq in scala.xml.NodeSeq.
    Shadowing
    This implicitly inherited member is shadowed by one or more members in this class.

  171. def zipAll[B](that: collection.Iterable[B], thisElem: A, thatElem: B): immutable.Seq[(A, B)]

    [use case] Returns a immutable sequence formed from this immutable sequence and another iterable collection by combining corresponding elements in pairs.

    [use case]

    Returns a immutable sequence formed from this immutable sequence and another iterable collection by combining corresponding elements in pairs. If one of the two collections is shorter than the other, placeholder elements are used to extend the shorter collection to the length of the longer.

    B

    the type of the second half of the returned pairs

    that

    The iterable providing the second half of each result pair

    thisElem

    the element to be used to fill up the result if this immutable sequence is shorter than that.

    thatElem

    the element to be used to fill up the result if that is shorter than this immutable sequence.

    returns

    a new immutable sequence containing pairs consisting of corresponding elements of this immutable sequence and that. The length of the returned collection is the maximum of the lengths of this immutable sequence and that. If this immutable sequence is shorter than that, thisElem values are used to pad the result. If that is shorter than this immutable sequence, thatElem values are used to pad the result.
